Comments about Smith & Wesson Smith Wesson Sigma Series .40 Factory Direct Replacement Magazine:
I recently got a S&W SD40 VE from Gander Mntn which came with two 10 round magazine (NY resident). I definitely wanted more 10 round mags before 4/15/13 when they can no longer be sold in NY. I read that the Sigma mags will work in the gun so I picked up the one extra they had on the rack and it works great. The rounds rattle in mag when it isn't in the gun but their quiet when in the gun.
Bottom Line Yes, I would recommend this to a friend
